To describe the pathophysiology, risk factors, and management strategies for small-for-size syndrome (SFSS) in living donor liver transplantation (LDLT), highlighting its impact on patient outcomes.
Key Findings:
SFSS is associated with a graft-to-recipient weight ratio (GRWR) < 1%.
Risk factors include donor age > 45, BMI > 30, graft steatosis, and high MELD scores, each contributing to the risk of poor outcomes.
Hemodynamic monitoring is essential to ensure adequate blood flow to the graft, with implications for graft survival.
Interpretation:
SFSS represents a significant risk in LDLT, necessitating careful management of graft characteristics and recipient conditions to improve outcomes and reduce complications.
Limitations:
Variability in measuring hepatic blood flow can lead to inaccuracies.
Existing literature may not fully encompass all risk factors or management strategies, and potential biases in studies should be considered.
Conclusion:
Effective management of SFSS in LDLT requires a multifaceted approach, including optimal donor-recipient matching and vigilant intraoperative monitoring, with a call for further research to refine strategies.
